WSI has collected Light Detection and Ranging (LiDAR) data of the Oregon West Metro Study Area for the Oregon Department of Geology and Mineral Industries (DOGAMI). The Oregon LiDAR Consortium's West Metro project area encompasses approximately 100,000 acres in Washington, Multnomah, and Clackamas County, Oregon. The study area includes the Beaverton, Hillsboro, and Forest Grove metro areas. Data were delivered in: Oregon State Plane North; horizontal and vertical datum: NAD83 (2011)/NAVD88 (Geoid12a); units: International Feet.
Between December 28th, 2012 and January 4th, 2013, WSI employed remote-sensing lasers in order to obtain a total area flown of 99,684 acres of which 96,543 acres comprise the area of interest. Settings for LiDAR data capture produced an average resolution of at least eight pulses per square meter.
In addition to LiDAR survey, OLC West Metro included high resolution aerial photography was acquired for the entire study area.
Lidar point clouds were projected back to geographic coordinates and ellipsoid heights for storage in the Digital Coast Data Access Viewer.

Vertical Positional Accuracy: |
A total of 1,776 measured GCP's were obtained in the Delivery region and compared with the lidar elevation grids. The data delivered to DOGAMI was found to have a mean vertical offset of -0.033 meters (-0.107 feet) and an RMSE value of 0.051 meters (0.166 ft). Offset values ranged from -0.210 to 0.153 meters For more information about the vertical accuracy, please refer to the final report, listed above in the Supplemental_Information field of this metadata record. ; Quantitative Value: 0.051 meters, Test that produced the value: Tested RMSE in meters in open terrain |
Completeness Report: |
LiDAR data has been collected and processed for all areas within the project study area. |
Conceptual Consistency: |
Upon receipt from vendor (WSI), all LiDAR data was independently reviewed by staff from the Oregon Department of Geology and Mineral Industries (DOGAMI) to ensure project specifications were met. All data were inventoried for completeness and data were checked for quality, which included examining LiDAR data for errors associated with internal data consistency, model quality, and accuracy. |
Lineage
Process Steps
Process Step 1
Description: |
The LiDAR survey utilized Leica ALS60 sensor mounted in a Cessna Caravan 208B. The systems were programmed to emit either single or multi-laser pulses at a rate of 61.1 or 63.3 Hz, and flown at 900 or 1500 meters above ground level (AGL), capturing a scan angle of +/-30 degrees from nadir. These settings are developed to yield points with an average native density of greater than eight points per square meter over terrestrial surfaces. |

Process Step 2
Description: |
The NOAA Office for Coastal Management (OCM) received the files in laz format. The files contained Lidar elevation and intensity measurements. The data were in Oregon State Plane North (NAD83(2011); FIPS 600; EPSG 6559) feet with vertical NAVD88 (Geoid12a) feet. OCM performed the following processing to the data to make it available within the Digital Coast: 1. The data were converted from Oregon State Plane North coordinates to geographic coordinates. 2. The vertical units of the data were converted from feet to meters. 3. The data were converted from NAVD88 (orthometric) heights to NAD83(HARN) ellipsoid heights using Geoid12a grids. |
